Disclosed is a method and apparatus for providing polyiodide resin-enhanced personal protective equipment (PPE) including but not limited to face masks, gloves, gowns and respirators. The disclosed method comprises the application of a polyiodinated ink polymer in or on one or more targeted surfaces of PPE to create a molecular sub-microscopic protective barrier between the equipment and the user. The disclosed system provides a PPE device capable of direct contact kill of organisms. In addition, the system provides for a sustained kill of organisms for up to 96 hours. The resultant PPE device is broadly effective against viral, bacterial, fungicidal and other microbial agents.

The invention provides a process for preparing bromine-containing polymers, comprising a Friedel-Crafts alkylation reaction of pentabromobenzyl halide with a polymer reactant which contains one or more six-membered aromatic ring(s) in its repeat unit, in the presence of at least one Friedel-Crafts catalyst. The so-formed bromine-containing polymers, having pendent CH.sub.2C.sub.6Br.sub.5 groups attached to at least a portion of the six-membered aromatic rings of the polymer, with a carbon ring atom of said six-membered aromatic ring being bonded to the aliphatic carbon of said CH.sub.2C.sub.6Br.sub.5 pendent group, are also provided. These bromine-containing polymers are useful as flame retarding agents.
